Research of the natural disaster risk on coastal cities

Natural disaster is the hotspot question in international society and academe. Natural disaster prevention is very important since the constant increase in intensity, frequency and extent of natural disasters. A coastal city is an important area and strategic focus of people convergency, national economy and society development, so the loss of the cities from natural disasters is very fierce and fatal. At present, the main questions discussed in this field are: types and risk identification of natural disasters, the indexes system and model of vulnerability assessment, natural disaster risk assessment and management, and the pattern of natural disaster data management. As the natural disaster risk assessment and risk management of coastal cities started relatively late in China, in the background of global warming and quick urbanization, our research in the coastal coastal cities should focus on these aspects: the indexes system and method of coastal city vulnerability assessment, the assessment procedure criterion and dynamic assessment model of coastal city natural disaster risk, the pattern and template of coastal city natural disaster data management, and the GIS tools of coastal city natural disaster risk assessment.
